DreamWorks Animation to Release MoonRay as Open Source
https://www.awn.com/news/dreamworks-animation-release-moonray-open-source
MoonRay is DreamWorks’ open-source, award-winning, state-of-the-art production MCRT renderer, which has been used on feature films such as How to Train Your Dragon: The Hidden World, Trolls World Tour, The Bad Guys, the upcoming Puss In Boots: The Last Wish, as well as future titles. MoonRay was developed at DreamWorks and is in continuous active development and includes an extensive library of production-tested, physically based materials, a USD Hydra render delegate, multi-machine and cloud rendering via the Arras distributed computation framework.
Note: it does not support osl and usd handling is limited. Cycles may still be a fair alternative.

Intel Open Image open source Denoiser
Intel Open Image Denoise is an open source library of high-performance, high-quality denoising filters for images rendered with ray tracing. Intel Open Image Denoise is part of the Intel® oneAPI Rendering Toolkit and is released under the permissive Apache 2.0 license.
The purpose of Intel Open Image Denoise is to provide an open, high-quality, efficient, and easy-to-use denoising library that allows one to significantly reduce rendering times in ray tracing based rendering applications. It filters out the Monte Carlo noise inherent to stochastic ray tracing methods like path tracing, reducing the amount of necessary samples per pixel by even multiple orders of magnitude (depending on the desired closeness to the ground truth). A simple but flexible C/C++ API ensures that the library can be easily integrated into most existing or new rendering solutions.
At the heart of the Intel Open Image Denoise library is a collection of efficient deep learning based denoising filters, which were trained to handle a wide range of samples per pixel (spp), from 1 spp to almost fully converged. Thus it is suitable for both preview and final-frame rendering. The filters can denoise images either using only the noisy color (beauty) buffer, or, to preserve as much detail as possible, can optionally utilize auxiliary feature buffers as well (e.g. albedo, normal). Such buffers are supported by most renderers as arbitrary output variables (AOVs) or can be usually implemented with little effort.
rayshader – open source tool for producing 2D and 3D data visualizations
rayshader is an open source package for producing 2D and 3D data visualizations in R. rayshader uses elevation data in a base R matrix and a combination of raytracing, hillshading algorithms, and overlays to generate stunning 2D and 3D maps. In addition to maps, rayshader also allows the user to translate ggplot2 objects into beautiful 3D data visualizations.
The models can be rotated and examined interactively or the camera movement can be scripted to create animations. Scenes can also be rendered using a high-quality pathtracer, rayrender. The user can also create a cinematic depth of field post-processing effect to direct the user’s focus to important regions in the figure. The 3D models can also be exported to a 3D-printable format with a built-in STL export function, and can be exported to an OBJ file.

“Autodesk is committed to helping creators envision a better world, and having access to great tools allows them do just that. So we are making RV, our Sci-Tech award-winning media review and playback software, open source. Code contributions from RV along with DNEG’s xStudio and Sony Pictures Imageworks’ itview will shape the Open Review Initiative, the Academy Software Foundation’s (ASWF) newest sandbox project to build a unified, open source toolset for playback, review, and approval. ”
Autodesk open sources Aurora – an interactive path tracing renderer that leverages graphics processing unit (GPU) hardware ray tracing
https://github.com/autodesk/Aurora
Goals for Aurora
- Renders noise-free in 50 milliseconds or less per frame.
- Intended for design iteration (viewport, performance) rather than final frames (production, quality), which are produced from a renderer like Autodesk Arnold.
- OS-independent: Runs on Windows, Linux, MacOS.
- Vendor-independent: Runs on GPUs from AMD, Apple, Intel, NVIDIA.
Features
- Path tracing and the global effects that come with it: soft shadows, reflections, refractions, bounced light, and others.
- Autodesk Standard Surface materials defined with MaterialX documents.
- Arbitrary blended layers of materials, which can be used to implement decals.
- Environment lighting with a wrap-around lat-long image.
- Triangle geometry with object instancing.
- Real-time denoising
- Interactive performance for complex scenes.
- A USD Hydra render delegate called HdAurora.

- Super-resolution Upscaler Diffusion Models
- Depth-to-Image Diffusion Model
- Updated Inpainting Diffusion Model
Open source Cycles render implemented into Gaffer
https://github.com/GafferHQ/gaffer/releases/tag/1.0.3.0
https://github.com/GafferHQ/gaffer/pull/4812
This release introduces support for the open source Cycles renderer. This is introduced as an opt-in feature preview intended for early testing and feedback as breaking changes can be expected while we continue to improve Cycles integration in future releases. As such, the use of Cycles is disabled by default but can be enabled via an environment variable. Additionally we’ve added support for viewing parameter history in the Light Editor, automatic render-time translation of UsdPreviewSurface shaders and UsdLuxLights for Arnold and made the usual small fixes and improvements.
Open Source OpenVDB Version 9.0.0 Available Now and Introduces GPU Support
First introduced in 2012, nowadays OpenVDB is commonly applied in simulation tools such as Houdini, EmberGen, Blender, and used in feature film production for creating realistic volumetric images. This format, however, lacks the GPUs support and can not be applied in games due to the considerable file size (on average at least a few Gigabytes) and computational effort required to render 3D volumes.
Volumetric data has numerous important applications in computer graphics and VFX production. It’s used for volume rendering, fluid simulation, fracture simulation, modeling with implicit surfaces, etc. However, this data is not so easy to work with. In most cases volumetric data is represented on spatially uniform, regular 3D grids. Although dense regular grids are convenient for several reasons, they have one major drawback – their memory footprint grows cubically with respect to grid resolution.
OpenVDB format, developed by DreamWorksAnimation, partially solves this issue by storing voxel data in a tree-like data structure that allows the creation of sparse volumes. The beauty behind this system is that it completely ignores empty cells, which drastically decreases memory and disk usage, simultaneously making the rendering of volumes much faster.
